The CRF-12 is a combination of the 12-ton articulating chassis and the Cemented Rockfill Slurry mixer (CRF.) The carrier is a self-contained machine that carries its own supply of cement slurry. This unit is an integral part of the CRF Backfill process, being able to quickly and sufficiently transport and batch cement slurry with minimal wash-down while being entirely controlled on a single carrier.
